Polymers for Optical Recording Media

Three roles of polymers in optical recording media can be distinguished: the recording layer, the protective coating, and the transparent substrate. This review focusses on the last role, and in particular on the problem of birefringence induced by polymer chain orientation and how to minimize this. Emphasis is placed on reducing the stress optical coefficient of polycarbonate type polymers by modifying the polymer structure or by blending polycarbonate with a second polymer.
